Heart failure poses a significant burden in urban China, with an estimated 12.1 million prevalent cases and 3.0 million incident cases among adults ≥25 years old.
BACKGROUND: Large-scale and population-based studies of heart failure (HF) incidence and prevalence are scarce in China. The study sought to estimate the prevalence, incidence, and cost of HF in China. METHODS: We conducted a population-based study using records of 50. 0 million individuals ≥25 years old from the national urban employee basic medical insurance from 6 provinces in China in 2017. Incident cases were individuals with a diagnosis of HF (International Classification of Diseases code, and text of diagnosis) in 2017 with a 4-year disease-free period (2013-2016). We calculated standardized rates by applying age standardization to the 2010 Chinese census population. RESULTS: The age-standardized prevalence and incidence were 1. 10% (1. 10% among men and women) and 275 per 100 000 person-years (287 among men and 261 among women), respectively, accounting for 12. 1 million patients with HF and 3. 0 million patients with incident HF ≥25 years old. Both prevalence and incidence increased with increasing age (0. 57%, 3. 86%, and 7. 55% for prevalence and 158, 892, and 1655 per 100 000 person-years for incidence among persons who were 25-64, 65-79, and ≥80 years of age, respectively). The inpatient mean cost per-capita was 4406. 8 and the proportion with ≥3 hospitalizations among those hospitalized was 40. 5%. The outpatient mean cost per-capita was 892. 3. CONCLUSIONS: HF has placed a considerable burden on health systems in China, and strategies aimed at the prevention and treatment of HF are needed.
